IIRC plugins are loaded once and then run within gmond's address space.
so I guess plugins could be causing memory leaks.
which plugins are you using? they alloc/free as they should?
we haven't notived any leaks (certainly no serious leaks) across our
~1800 gmonds using 3.2.0, but we aren't sending that many metrics
either - just using most of the standard stuff plus modified diskstat,
cputemp python plugins, and with a bunch of other metrics spoof'd from
chassis and switches (more cpu cycles for HPC job this way).
we are using multicast.
all except a few gmonds (not included below) are senders only.

those with the larger RSS have been rebooted recently and haven't yet
had unused pages pushed out by vm pressure.
